Procedure

2 lbs of Harcombe pale malt was crushed in a coffee grinder. I know, I know... not a good idea. Learned the hard way here.

 

Dough-in at 130F (1 gallon water), cooled to around 125. Steeped for 20 minutes at 125F. Raised temp to 144F by boiling water addition (probably 2 qts). Held temp for 20 minutes. Raised to 154F, held for 30 minutes. Mash-out at 170F for 10 minutes. (n.b. 1 gallon volume was REALLY hard to maintain temperature.)

 

Boil for 60 minutes. 1 gallon was nice for getting a nice hard boil. 

 

Finings (1/4 tsp) and nutrient (1/4 tsp) added at 15 min out.

 

Chilled outside (ambient 5F) to 65F.

 

Pitched onto BRY-97 starter.
